You’re absolutely right. I didn’t read over everything and hadn’t realized these are alkaline, not rechargeable. I had a dunderhead moment, sorry. :confounded:
Does IKEA make a decent NiMH cell in AA and AAA format?
I have used Ikea NiMH AA in my Logitech mouse for over 1 year, giving 10 days runtime under relative hard use. The Ikea AA Alkaline seems to give some days longer runtime than the NiMH. I dunno why, though.
Also I think the NiMH batteries last some longer charging them in the new Liitokala 500S. This could be placebo effect, as I like the new charger better
Alkalines are 1.5V while NiMH are 1.2V. I think that is responsible for the difference.
My Logitech M720 specifies 1.5V. The official specs say 2 years battery life on one (alkaline) AA, but I got 4 months out of it with my use. With an Eneloop I got about half that. The mouse goes dead at ~1V.
Logitech Performance MX. Wow 4 months, think I soon will get a new mouse.
The usb receiver is placed 1.30m from the mouse, that can be the reason for short runtime.
I recommend the MX Master, if you don’t mind the larger size. Excellent mouse and seems to be very good runtime. Has 3 LED dots to show you more informative charge level than green/red.
Alkalines has better capacity at very low currents. See tests done by HKJ. Modern mouse uses less than 10mA of current. So it’s expected that alkaline will last longer. However, with frequent use, I think it makes sense to use NiHM and recharge still.
